Question
The motivation of Residual Networks is that very deep networks are so good at fitting complex functions that when training them we almost always overfit the training data. True/False?
Solution
False. The motivation behind Residual Networks (ResNets) is not because very deep networks overfit the training data. Instead, ResNets were designed to solve the problem of vanishing/exploding gradients and the degradation problem, which are common issues when training very deep networks. These problems lead to a saturation of accuracy and make the network difficult to optimize. ResNets introduce "shortcut connections" or "skip connections" that allow the gradient to be directly backpropagated to earlier layers, making it easier to train deeper models.

Training a deeper network (for example, adding additional layers to the network) allows the network to fit more complex functions and thus almost always results in lower training error. For this question, assume we’re referring to “plain” networks.

Which is false?Group of answer choicesOutput of a layer in the residual network is the normal output (i.e, what’s produced after applying a filter and an activation function) + the layers input.Output of a layer in the dense network is the normal output (i.e, what’s produced after applying a filter and an activation function) + the layers input.Output of layer 𝑙 in the dense network will be one of the inputs for layers 𝑖∈(𝑙+1,𝐿) where 𝐿 is the total number of layers.A problem of convolution network is that some features may get extracted earlier in the network, but could be useful later on. However, it is hard to keep track of previous non-modified outputs.
